Brief: A warm, solid, passive solar beach house on a lifestyle block including a large home office. Specifically not timber frame construction. As sustainable and energy efficient as possible. To have solar panels and a wood fire with wetback and water heated floor. There was a requirement for the house to have a floor level 1.3m above ground level due potential for flooding in the area.
Waikuku Beach House is an Insulated Precast Concrete Panel House. This is optimum construction type providing thermal mass, comfort and permanence resulting in a very cosy home with low running costs. Panel junctions and openings have been detailed to provide a continuous insulation envelope with no breaks. Warm water heats the floor, which is thermally isolated using a separate topping slab on high performance foam insulation. Dark tiles to the perimeter assist with heat absorption with bamboo flooring elsewhere. The house has high performance windows with Low E argon gas filled glazing. Large over hangs protect from over heating.
Strong horizontal lines help disguise the unusually high floor level. As well as designing the house to capture the suns energy and keep it in, fitting the house to the site, capturing the views and providing sheltered courtyards for protection from the wind on two sides have been key considerations.
